Power Query / Power BI Consultant for Businesses That Run on Excel
M pipelines that survive the refresh. Power BI dashboards when your team needs self-serve filters and drill-down..

Most Power Query pipelines die the same way: somebody hard-codes a sheet name, the source changes, and the refresh breaks silently for two months before anyone notices. Or the M-code is written so cleverly that nobody on the team - including the person who wrote it - can read it six months later.
I write M-code that names every step in plain English. Picture a logistics team with four carriers, three warehouses and a CSV from each: one Power Query pipeline pulls them all, deduplicates on the waybill, validates the freight cost column and ships a per-shipment table the dispatcher actually opens. See how the logistics work is scoped.
Power BI when the engagement needs self-serve. Power Query alone when Excel is enough. The right answer is whichever your team will actually open on Monday morning.
What I do
How a Power Query / Power BI engagement runs.
Multi-source M pipelines
Pull from ERP exports, CRM exports, REST APIs, SQL databases and CSVs into one tidy table. Refresh on a schedule. Document every step.
Star-schema data models
Power Pivot data model with proper relationships, surrogate keys and slowly-changing dimensions. DAX measures that read top-down.
Power BI dashboards when self-serve is needed
If your team needs to filter by region, period and entity without rebuilding the dashboard, Power BI is the right surface. I build the .pbix and hand it over.
Validation that fails loudly
Null IDs, negative amounts, missing sources, out-of-range dates - caught at the pipeline step, before a wrong number reaches the report.
Free Self-Serve Excel Tools
Interactive in-browser calculators and diagnostics. No sign-up, no email required.
Workbook Compare
Drop two versions of a file and see every changed cell and formula, inserted rows, and formulas someone typed over.
Workbook Map
See how your sheets feed each other as a diagram, with links to other files, hidden feeders and circular links flagged.
Formula Explainer
Paste any formula and read it in plain English, step by step in the order Excel calculates it.

Common next step
Pair this with Excel Data Cleaning when the pipeline needs explicit validation and dedup steps before it feeds the model.
Process
Three stages, fixed scope.
- Step 01
Diagnose
Source inventory, refresh cadence, who opens the report and on what schedule. A short call answers most of these in 30 minutes.
- Step 02
Architect & build
Data model and refresh strategy agreed in writing. Pipeline is built in short loops against your real source data, not a sample.
- Step 03
Hand over
Recorded walkthrough, written spec, documented M-code. Your team can run, audit and extend the pipeline without me.
Frequently asked
Before you hire a Power Query consultant.
Power Query or Power BI - which do I need?
If your team opens Excel and reads numbers, Power Query alone is usually enough - the pipeline runs inside Excel and ships a refreshable workbook. Power BI makes sense when your team needs self-serve filters, drill-down across many visuals, or a published dashboard on the web. I build both.
Will it work with my Excel version?
Power Query is built into Excel 2016, 2019 and Microsoft 365 on Windows. Power BI Desktop is free. If you are on an older Excel, the engagement starts there - and I design the deliverables to work with what you actually have.
